Determine the quantities of earthwork for the portion of a road between chainages and 60 from the following data, length being measured with a standard 20 m chain:-
The formation level at chainage 50 is 130.0 and the road is in a rising gradient of 1 in 200. The width of formation is 10m and side slope is 1.5:1 in embankment and 1:1 in cutting, the lateral slope of the ground may be assumed as level. calculate also the cost of this earthwork in bank and cutting. Assume suitable rates and also draw the mass diagram.
